I personally think that it isn't really real. Love at first sight is basically falling in love with them because you think that person is good looking. Hence the term, love at first SIGHT. First time you see them. True love is based off... you know. Mushy stuff.
In my personal opinion, I don't think it's possible. Rather, the feeling of "love at first sight" is a strong attraction. You cannot love someone if you don't even know the person! It would merely be based off of physical appearances.
Love at first sight means when you see someone you are instantly attracted to them. You are attracted to their looks at that moment you may not know anything about them but just are astounded by their beauty. This isn't love this is just simple physical attraction. Love is different to everyone in this world. But, when you love someone you accept them for their inner and outer being, their past and future decisions and you want them to be the best they can be while you take their hand in their journey of life and they are willing to do the same. You can't determine all that acceptance by just one look it takes a lot of trust and special moments to do that.
It's possible because of the spiritual connection. We all have familiar spirits and those who are saved have the Holy Spirit. My brother loved his wife when he first saw her. They have two sons and a grandson now.
Yes it is its the immediate feeling you get the first time you meet or see them I met a boy before when I was on holiday I spotted him on a balcony and he caught my eye later that day we walked past each other in the hotel reception and as we walked past each other we both stopped and turned around and just smiled he said hi but I got shy and ran off anyway we got together and it worked out etc etc and yes I love him very much
